Awesome! Thanks for being brave enough to try the dummy client.

Yep, I'm not sure how to handle that. Switching between intel and
nouveau switches between two frame buffers drivers. I assume we could
use a standard vga console with nvidia w/o nouvea, as happens when you
flip the switch in the bios, but I'm not sure how to reverse the
vga->fb switch. I wonder if we could activate vesafb on the nvidia
card and still have the nvidia driver work.

I'm glad it's an improvement for you. I've heard some reports that
flipping the IDE compatibility mode switch in the BIOS to get only the
nvidia device visible hurts disk performance, so maybe this will be
faster for you in that respect. If you have any scripts to share, I'd
be happy to add a contrib directory to my asus-switcheroo repo.
Thanks,
